Deerfield, Massachusetts: 30% RAP from 30-Penetration Asphalt with SIP-1111™

Saturday, 25 July 2026 / Published in Demo Projects, SIP-1111™, SIP-1111™ Rejuv
Two crew members rake fresh asphalt on a rural road beside a harvested field.
The Lower Road demonstration used SIP-1111™ to formulate PG 58-28 binder from hard 30-penetration asphalt. The 30% RAP mix raised the reported cracking-test indices and recorded 5.1 mm Hamburg deformation versus 4.5 mm for the 15% RAP control at 45°C.
